In accordance with the invention, the general objectives are obtained by providing an article of footwear in which upper sections are detachably attached to sole sections and means are employed to maintain said upper sections in desired attached positions and to release them from said positions as desired, Slidable attachments, resilient sections and movable sections as well as other features are employed.

The features of my invention apply to footwear of every kind. Details, sach as the construction of the sole, can vary. For instance, a sole may have a single layer in some footwear while in other footwear a sole may consist of an outersole, nnersole, shank tack, and heel tuck all cemented together.

FIG. 15 is a lengthwise section illustrating another embodiment of the invention; and

FIG. 16 is a fragmentary top plan view of the rear part of a shoe in accordance with my invention.

The shoe illustrated by iFIG. 1 consists of a generally indicated sole 20 to which a vamp 21 is attached and a generally indicated heel section 22 is detachably attached. The socket 23 depressed in the sole 20 opens rearwardly and the socket 24 opens forwardly, thus opening in opposite directions. The heel upper section 2S is attached to section 26, which rests on the sole 20. Stud 27 in the heel area of the section 26 and stud 29 in the shank area of the section 26 connect section 26 to sockets 21 and 23 respectively. The openings in opposite directions together with the `elastic area 33 provide means for attaching and detaching conveniently and maintaining the attachment while providing slidability and holding the heel section in the socket.

LFIG. 2 shows a shoe similar to the shoe of FIG. 1, but with the sockets 3S and 36 facing toward each other. The material 37 attached to the upper 38 and resting on the sole 39 is detachably attached by studs 40 and 41 to the sockets 35 and 36 respectively in the sole 39 and is bendable in an upward direction to allow it to -be slipped out of the sockets. The material 37 should preferably combine irmness 'with flexibility and preferably a significant amount of resilience, with a tendency to straighten out to the level of the sole. The section ibetween the sockets can be contractable, as in the section 109 of FIG. 16 in a similar situation to be described later. p

FIG. 4 is a top plan view and FIG. 5 is a section, approximately along the line 55 of FIG. 4, of the rear part of a shoe, showing a rear section of sole layer 42 and a heel upper section generally indicated at 43 with upper section 44 and material 4S connected to upper ma# terial 44 and resting on sole layer 42 and attached thereto by stud 47 in socket 48. The upper layer 49 of material 45 is shown in FIG. 5 to be bent up to display a down.- ward protrusion or bar 50 designed for positioning an aperture or channel 51 in sole layer 42 adjacent to the front edge 52 of lower layer 53 of material 45, in which position, in conjunction with the firm bent-up section 54 of layer 49, it will serve to oppose the sliding of stud 47 and of socket 48. The bar 50 is shown as being made of resilient materialsuch as polyurethane foam for snug lit, but non-resilient material may be used.

In FIG. 6 a heel section 55 is detachably attached by stud 56 to socket 57 depressed in sole Vlayer 58, with a layer of material 59 attachable to upper portion, 60 of the heel section 55 and resting on sole layer 58 in the heel area extending forwardly to butt up against Vthe rear edge of top sole layer 61 at juncture point 62. Both the front edge of the layer 59 and the sole layer 61 are showntobel of resiliently compressible material, 59A and 61A,..re spectively. As shown, either or both edges can be matieV resiliently contractible, but they need not be. The dottedV line position of the layer 59 in FIG. 6` indicates how that layer can be bent up, even though itvhas a-fsubstantia1 degree of firmness, t0 permit the heel section to `slide forward and the attaching studV 56 to slide out ofthe socket 57. l e

FIG. 7 shows a sliding bar 64 which may slide out of 1e Way of the bottom material 65 of heel section 66. [ere also the bar 64 may be resilient as shown or may e non-resilient.

'FIG. l8 shows a sole layer 67 pivoting or binding up- 5 'ard at 68 and having a bar 69 attached to its underside )r positioning in channel 70 to oppose the forward slidlg of heel section 71. The upward-pitched portion 72 of Lyer 67 is firm enough to oppose the forward sliding of eel section 71 and the sliding of stud 73 out of socket 74 part from the bar 69.

FIG. 9 shows a socket 75 depressed in sole layer 76 and lcluding a slidable block 77 positioned adjacent to stud 8. Top sole layer 79 is shown bent up with block 80 ttached to the underside for positioning in socket 75 to iaintain slidable block 77 adjacent to stud 78 so as to preent stud 78 from sliding out of socket 55. When block 77 slid forward to the position indicated in dotted lines, it :aves open space enou-gh for the stud to slide out of )cket 75. The blocks are shown as resilient but may be on-resilient.

FIG. 10 shows a resiliently compressible block y82 in )cket 8G opposing stud 84 from sliding out of socket 83. hen the block =82 is sufficiently compressible, stud 84 an slide over it into or out of the socket.

FIG. 11 shows a resilient block 85 in the socket 86 etween stud 87 and closed end 88 thus affording a rear ishioning effect for comfort when the foot presses against 1e rear upper part of a heel section. It also is a way of roviding adjustability in t.

FIG. 12 and 13 shows a layer of material 89 having an longated narrow slot 90 closed` at the rear and open at 1e front for sliding between the sole layer generally ldicated at 91 and the bottom 92 of a heel upper section, 1e sides of the slot 90 being adjacent to the narrow neck E the stud 93. The sliding layer of material Iis designed )r slipping into position after the heel upper section is etachably attached to the socket 94. It serves to provide snugness that opposes Wobbling or rocking.

FIG. 14 shows two studs 95 and 96 in socket 97. The ffect is similar to that of two separate sockets with a stud l each, insofar as pertains to the opposing of the side- 'ays turning of the heel upper section to which the studs re attached. A plurality of studs or sockets can also be sed in other of the examples shown in the drawings.

tFIG. 15 shows the firm bottom layer 98 of the heel action 99 extending forwardly and bending upward from pivot point at the front edg'e 100 of the heel section 101 E upper 99. The layer 93Y is shown to have a downwardly rojecting part `102 attached to the underside for posioning in the aperture 103 in sole layer 104. At 105 a iagnetic material is shown attached to the layer 98, and t 106 a magnetic or complementary material is shown ttached to sole layer 104, the two serving to hold down yer 98 with bar 102.

FIG. 16 shows a top plan view of a sole, generally ldicated at 107 with a raised sole layer section 108 having rear edge 109. At 110 is generally indicated a heel section aving an upper section 111 and a section of bottom iaterial 112 attached to upper section 111 and to the :le by stud 113 in socket 114 in the heel area and resting n sole 107. The section 112 is shown extending forward l the form of a sleeve 115 enclosing a narrower tongue E material 116 which widens into a wide section 117 hich butts up against the rear edge 109 of raised sole .yer section 108. At each side of the sleeve 115 is elastic .aterials 118 and 119 butting up against the shoulders l and 121, respectively, of the lwider section 117. The astic material can be stretched to allow the sleeve 115 slide over section 117 or conversely, to allow section l7 to slide into sleeve 116, thus permitting the bottom :ction of heel 112 to be contracted so as to permit stud l3 to slide out of socket 114.

'From the foregoing it will be seen that footwear in :cordance with the invention will be improved in vari- 75 ability, functioning, comfort, and adaptability as well as other features.
